[image] Aerial view of Forest. Carbon uptake and storage is one of many ecosystem services that forests provide. In the United States, forests and associated harvested wood products uptake the equivalent of more than 14 percent of economy-wide carbon dioxide (CO2) emissions each year and store more than three decades of CO2 emitted from fossil fuels. The FIA program has responsibilities for delivering policy-relevant reports, tools, and data on CO2 and other greenhouse gas (GHG) emissions and removals from forest land as well as trees outside of forest (e.g., urban forests, grasslands) in the US. Principally, the FIA program is responsible for compiling estimates of GHG emissions and removals from forest land, harvested wood products, urban trees, and woodlands in the US each year as a component of the National Inventory Report that is submitted to the United Nations Framework Convention on Climate Change. The FIA program also develops and contributes GHG estimates to several local, state, and national reporting instruments such as the US Biennial Report, the US Resource Planning Act Assessments, and the Montreal Process Criteria and Indicators.

Land carbon science within the FIA program is targeted at improving the methods and models used to characterize carbon in the land sector and also to improve the spatial and temporal resolution of estimates of carbon stocks and changes to facilitate evaluation of existing land management policies and practices and to inform future activities. This work is done in collaboration with partners and stakeholders to enhance capacity and deliver relevant science, reports, and data.

This page provides an overview of forest carbon science and reporting in the FIA program along with links to research and reports.



FIA Carbon Reporting

The FIA program leads and contributes to several carbon reporting activities. This section provides recent examples of FIA contributions to international, national, state, and entity-level reports. Additional reports can be found in Treesearch.


International Reporting

The FIA program contributed database estimates, science, and expertise in these recently released international reports:

National Reporting

The FIA program leads and contributes to science and reporting on the economy-wide GHG emissions and removals as well as projections of future emissions and removals.

State Reporting

The FIA program leads and contributes to regular state level carbon reporting.

National Forest System Reporting

The FIA program leads and contributes to regular National Forest System carbon assessments.

Entity-level reporting

The FIA program leads and contributes to regular entity-level carbon assessments.

FIA Carbon Science

Estimating carbon in forest ecosystem pools

The FIA program leads the development of methods and models used to characterize carbon in forest ecosystem pools. Many of these methods and models are used in reporting activities or to estimate carbon variables in the FIA database.

Integrating remotely sensed information in carbon estimation

Many different approaches for data harmonization and fusion are being tested to improve the spatial and temporal resolution of forest ecosystem carbon stocks and changes.

Assessments of uncertainty in carbon estimation

Identifying sources of uncertainty in estimates of carbon stocks and stock changes helps to inform investments to reduce uncertainty.

Attribution of carbon flux in forest ecosystems

Attribution of carbon stock changes to human activities and natural processes informs policies and management strategies aimed at avoiding emissions or maintaining and enhancing carbon stocks and sequestration in forest ecosystems.

Land representation

Land use and land cover classification and representation is foundational in estimating carbon stocks and stock changes within the land sector.
